Hello Folks! Welcome to Our Blog.

So of course I wanted to know what happened, what went wrong? My guess is either his download corrupted and he skipped checking the MD5 checksum or something went wrong with the flash.

I had a hunch the rootfs of his router was corrupted in some way, and the boot-loader would still work. Because a sysupgrade procedure only touches the rootfs as far as I know. While doing some research on debricking I learned that it would be possible to reflash the rootfs from the boot-loader over TFTP.

This is fairly straight-forward, but some instruction how to do it for the first time comes in handy.

Soldering the header to it requires a good soldering iron with a small tip. I had trouble with it, but eventually got it done with an extra pairs of hands and an extra soldering iron for some more heat.

Start your serial console of choice and configure it for a baud rate of 8 data bits, No parity, 1 stop bit, no flow control, all are often defaults. Set it to Serial mode and told it to use COM3 as the communication device. Once your serial console it running, power up your router and watch the console for output.

On my first attempt I got no output. I needed to reverse my RX and TX connectors, once I did that and re-powered the router it worked immediately. It will interrupt the boot process and give you a minimal shell in the U-Boot boot-loader to send it commands. I used a Linux box I had laying around for this. Use ip addr or ifconfig for this.

I had no time for exploring and parsing the binary file, so I decided to rollback in order save my settings in a plain text file and than flash the DD-WRT firmware again.
